The world is in chaos as a powerful Bio-Beast named Godkaiser Hell has brought destruction to Earth in 1999. The once thriving planet lies scarred from a catastrophic nuclear and biological attack, with most survivors forced to flee underground for safety. As the Bio-Beast's army of monsters ravages the surface, hope remains in the form of Dr. Kabuto's groundbreaking creation: the Mazinger-Z mech.
The player takes on the role of the suit's pilot as they embark on a quest to reclaim their home planet from the monstrous forces. With swift movements controlled by the D-pad and precise slash attacks using face buttons, the battle against the enemies is intense. A limited Super Attack option is available, but it comes with a price: each use reduces health levels.
